ÖNORM EN ISO 29461-4

Issue date: 2025 11 01

Air intake filter systems for rotary machinery - Part 4: Test methods for static filter systems in coastal and offshore environments (ISO 29461-4:2025)

This document defines test methods for performance testing of individual filter elements and of the complete filtration system.1) This procedure is intended for filter elements and filter systems which operate at flow rated up to 8 000 m3/h per filter element. 1)  The filters will be loaded with ultra-fine salt particles of a size mostly sub micron during variable humidity to simulate real offshore and coastal conditions hence filters with an initial conditioned efficiency lower than 50 % for the ePM1 particles (filter class T7) are likely to underperform and would not be suited as a single stage filter.

Frequently Asked Questions about ÖNORM EN ISO 29461-4

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
